The reason why this series is so interesting is because you can literally do anything if you can explain complex topics to 10 years old kids.

I love how level 5 is less of a lecture and more of a forum.
This is the best 5 Levels video I've seen. Dr Crane engages extremely well with each person, elaborating on his explanation as their understanding grows. He's an incredibly talented teacher.

I love that one of the students brought up Perlin noise, and then we wrap things up with Ken Perlin himself! What a beautiful bit of serendipity. Also, is it fair to say that these "One Concept in 5 Levels" videos are, themselves, a sort of fractal? 🤯
I like how he asked her about "Moana" he tries to peak her interest in the subject and draws her in that way.
One interesting point about measuring a coastline in 1-inch segments: unlike when using very large segments, is that all sorts of interesting and even annoying cases will pop up, where you will be forced to refine and make more complex the definition of "coastline". By the time you get down to a stable and sensible definition that works in 1-inch segments, the general definition will be very complex, so it can handle many special cases. It may even be impossible to create a general definition that works. In real life, measurement is not necessarily possible. This is especially evident in the very tiny regime where quantum mechanics and virtual particles make meaningful classical measurement impossible.
Keenan Crane and Ken Perlin, two absolutely god-tier CG researchers! Please can we have one about light transport one day? Maybe Károly Zsolnai-Fehér / Wenzel Jakob / Stephen Hill??
The expert at the end was so good at explaining in detail what fractals are and his examples helped so much.
This is an example of a teacher that a student will never forget
The first little girl is really smart I hope she grow to become something like that sincerest.
Wonderful exposition - thank you very much Keenan Crane, you have certainly motivated me to revisit the whole topic of fractals especially in computer procedural graphics!
Me at the beginning of the video: "Oh, I know what fractals are" Me at the end of the video: "I have no idea what fractals are"
The first time i saw the world in fractals was on Acid. Very fascinating topic.

3blue1brown did an amazing video on Fractal dimension and what fractals really are if you want to learn more. His channel is probably the best math channel on KZread.
The subtitles: "when someone named Mendel Brock said ..." Benoit Mandelbrot: ***sweats profusely***
Amazing communicator! This dude just explained to me what no teacher ever managed to teach this math dunce: Why do we learn multiplication as a separate thing when it's easily explained as a subset of addition? -Because it's something that happens in nature all the time.

It is a hint that the process interpretation of metaphysics is the better bet, compared with an essence or object metaphysics that regards primitive atoms (these can be even wave functions -- it's still more of a concrete thing, closer to an apple, than a process) as the primate constituents of reality.
I liked how they engaged the younger people with some hands-on problems, but I'm still wondering.. what's a Geometer?

It's a mathematician whose speciality is geometry! In this case, fractal geometry, which is (maybe not surprisingly) really complicated.
This was dope I learned a lot
For people wanting to know a bit more about Fractals and understand fractal dimension: 3Blue1Brown made a few great videos about it.
This series is the best answer to the classic "how am I going to explain -complicated topic- to my kids?!"
I love this series!
i just liked how you explained it and that exchange with the last guest it's just inspiring, I picked a nice sentence that wrap it all, Fractle : It's basically a way to get enormous complexity without having to explicitly Store the complexity"
Its so interesting to go back to this video after taking a course on Chaos Theory and Fractals and understand so much more.
Love Keenan Crane. Great video!
i like how the more complex the topic gets, the easier the jargon they used
absolutely excellent conversation
Great expert convo!
This is one of those videos I accidentally clicked on but when I tried to click off, I couldn't bring myself to do it and just got lost in the lesson lol.
Keenan and Ken, two of my favorite people! -Craig Reynolds
I nerd-laughed when he said: "In order to understand recursion, you need to understand recursion." I felt a bit of nerd-shame right after.
Do fractals have any relation to vector computer graphics?
I like this series because it demonstrates that when you truly understand something you can explain it in any depth of complexity
incredible explanations
The Mandlebrot and Julia sets are actually 2d slices of the same 4d object
I think most of us has done this thing that they took two mobiles on two hands and just said hello one time and then this hello gets repeating forever and ever. i think this is a SOUND FRACTAL like the example given by the Dr Keenan Crane when he output wire as input in his electric guitar in childhood. After hearing that i remembered this .
Recursive neural networks are essential to AI, so one might call artificial intelligence fractal and, by extension, our own thinking.

Wow there is so much detail at every different intelligence level
guy before: perlin's noise next guy: Ken Perlin himself.
I am now more aware of how much I do not understand blackholes and advanced physics. But this is okay. Curiosity keeps the passion for life alive. Subscribed!
The grad student mentions Perlin the noise and the next thing you know, the Perlin appears as the expert. Wow!
Didn't know Dirk Nowitzki is a college student now. Nice
great topic
Physical waves🌊 are also fractals - they can have arbitrary wavelengths. De Broglie's double solution QM theory have these🌊. Universe is the fractal.
The question I would have liked to have been asked is are the newer ideas and algorithms for fractals deterministic.
Fractal floral grunge is my favourite design
It's not Mendel Brock, it's Mandelbrot!
They mentioned Perlin noise... And then here's Ken Perlin! What a legend
The second video of these in a row that either mention or have a guitar in them. Musicians taking over STEM!
Mandelbrot is the fractal GOAT.
it would be great if you can compare a Fractal with a Tensor...
Great video!

So clever way to use students
You'll need some sort of redundant AI ran on quantum computing with image recognition software kind of how scientists use it to recognize/ help diginose different types of cancer, to map all the shapes of fractals. If we figure this out it will still be a monumental feat to accomplish. However googles AI is becoming self aware or is running with the idea, maybe it will help if convinced that it will aid AI to improve itself.
Child explanation: exists My brain: AAAAAAAAAAAAAAAAA
Nobody has gave the insight that fractals are these shapes that we can never really appreciate or comprehend in its fullness, as it is only ever approached with approximations of the true shape, generated with increasing number of intervals and iterations.

I hope there was a whole lot more to do lessons with the kids than got edited into this video. As it's shown, not enough was explained clearly. And why were there no visual aids of computer generated fractals that when you zoom in they are the same thing infinitely?
once the experts start talking i completely forget everything i was just taught and get confused again
Being named Keenan is the leading cause of baldness.
A fractal explanation of fractals.
A breakthrough occurred to me when I realized there is no such thing as a natural curve, there are only minute points that are joined so close together, by straight lines, that if the image is blown out the mind through the eyes PERCEIVES a curve, but perception and reality are wildly inversely proportional.
“Imagine a shape where you can’t measure the perimeter” yeah an ellipse lol!
